1. A thin film transistor array panel comprising:

  • an insulating substrate;

    a first signal line formed on an insulating substrate;

    a first insulating layer formed on the first signal line;

    a second signal line formed on the first insulating layer and intersecting the first signal line;

    a thin film transistor connected to the first and the second signal lines;

    a second insulating layer formed on the thin film transistor and having a first contact hole exposing a electrode of the thin film transistor; and

    a pixel electrode formed on the second insulating layer and connected to the electrode of the thin film transistor though the first contact hole, wherein at least one of the first and the second signal lines comprises Ag alloy containing Ag and an additive including at least one selected from the group consisting of Zn, In, Sn and Cr.
